[header] How to call deer [title] Use a bleat can to emulate the sound of does and fawns. [step] A bleat is a drawn out sound similar to a cow's moo. Does and fawns, or female adult deer and young deer, make this noise to communicate with one another. <sep> (A) Some hunters find it easier to make a " double " sound. The sound is also rather sharp and alien to the mammary glands. (B) Bleat cans replicate the sound of a deer and can be purchased at a hunting store or online. To use it, simply flip the can over to make the sound. (C) If you are female deer, you can pull your hood up and use a goggle-face mask to send out a bit of the sound. [substeps] Deer should do this before heading into the dark woods, at dawn. (D) When the female deer feeds on a feed, the young deer will signal to others to gain attention and quiet the herd or chase them down. As long as the female deer is excited and continues to graze, she will eventually stop calling to other deer and return to her normal schedule.
